A fan-coupling device with a unitary magnetic pole is disclosed. The magnetic pole is of a unitary, ring-shaped construction and includes a choke space and a ridge that promote an increased amount of magnetic flux generated by an electromagnet to travel to a magnetic armature on a fluid flow valve, resulting an increase in the amount of magnetic force that acts upon the valve. This is an improvement over the prior art two-piece magnetic pole structure and over a unitary magnetic pole without the choke space and ridge. The magnetic pole also includes apertures in which protrusions on a sound dampening gasket are inserted to reduce the noise resulting from the armature striking the magnetic pole.

A bi-directional pressure relief valve for a plate fin heat exchanger including an elongated heat exchanger tube having ends and a channel for the flow of a fluid from one end of the tube to the opposite end and a bi-directional reed valve positioned within the channel. The reed valve allows fluid to flow within the channel in either direction when a pressure differential across the reed valve is sufficient to urge the reed valve to an open position, thereby enabling the heat exchanger to be used independent of the direction of fluid flow through the heat exchanger.

A viscous fluid clutch assembly used in automobiles, SUVs, and trucks minimizes flow back of the cooling fluid from the reservoir towards the working chamber of the clutch when the vehicle is at rest and avoids excessive fan noise, wasted power and fuel inefficiency when a cold automobile engine is started. The clutch utilizes a discharge channel extending from the periphery of the working chamber to the reservoir and a specially designed ball check valve at the entrance to the reservoir which is open or closed depending on operation of the vehicle. The ball check valve is fluidly connected to the working chamber of the fluid clutch by a preferred articulated discharge channel which starts at the working chamber of the fluid clutch and ends at the reservoir of the fluid clutch.

A fluid cooling device carrying cooling fins thereon also carries a plurality of series of plates one above the other. Each of the series of plates is composed of an upper and a lower plate which are in spaced relationship with one another. The space between the upper and lower plates of each of said series of plates define a channel therewithin which is connected to the corresponding channels in each of the series of plates with all of said channels being also connected to inlet and outlet openings. The portions of each of the plates within each of the channels defined therein carrying projecting baffles therewithin which are adapted to cause turbulence in the fluid to be cooled which passes through said channels from the inlet opening to the outlet opening of the device.
